To allwhom it may} concern; y Be it known that I, ALBERT R. BEHNKE,

a citizen of the United States, residing at" St. Paul, in the county of Ramsey and State of Minnesota, have. invented certain new and useful Improvements in Removable Rims, ofwhicli' the following is a specification.

My invention relates to-improvements in tire carrying rims, its object being to provide a longitudinally split removable tire carrying rim with improved means forlook- .ing the sections together, whereby the sections may be quickly and easily locked together or disconnected from each other to ported upon or removed from the rim.

My improved rim with a supported tire may be secured upon a wheel by the ordinary fastening devices. i.

To :thisend the invention consists in the features of construction, combination, andarrangement of parts hereinafter described and claimed.

In the accompanying-drawings forming part of this specification, Figure 1 is a side view of a rim embodying my features of invention; Figs. 2 and ,3 are sectional views casing and tube.

formed with a plurality of openings 5, which through the rim sections; Fig. 4 is a detail view of my improved rim" shown broken away and sectioned; Figs. 5 and 6 are side 1 and top views," broken away, of a locking ring forming part of the invention; and Fig. 7 is a section on line wm of Fig. 5.

Referringto the drawings, 2 and 3 represent annular clencher rim sections which, as shown in Fig. 4:, overlap to form a clenoher rim of the ordinary type having curved edges 4 to receire the tire flanges' The underlapping section 3 preferably overlaps the entire inner face ofthe section 2 to. constitute a smooth bearings'urface for the The rim sections are openings register when the sections are placed inpverlapping position.

For the purpose of locking together the rim sections I provide the spring ring 6 havunconnected ends whereby it may be Copies of this patent may he ottainec for Specification of Letters Patent.

' sprung to fit tightly. inside the rim. The

ring is formed with a plurality of outwardly bent tapered lugs 7 spaced a distance apart equal to the spacing apart; of

the slots 5.

In use, with. the sections of the clencher rim placed over the side beads of the tire and b roug ht together into the position shown 111 Fig. 4, the locking ring is inserted inside the rim with the lugs 7 positioned opposite the slots 5 andthe ring then allowed to expand to allow the lugs to extend Patented Mar. so, 1915.

outwardly through. the slots, holding the rim sections together. The tapering of the lugs facilitates their entry into the slots, the

lugs being inlength equal to the combined thickness of the two sections ofthe rim, so

as to project through the registering slots in both without projecting beyond the inner rim sections to injure the tire. With the sections of the rim 6 thus secured together the rim with the supported tire may bearranged upon the felly of the wheel and secured thereon in the usual manner.

-By means of my invention I am enabled to carry an inflated tire upon the rim ready for placing upon a wheel, and to support a tire upon the .rim and to remove the same therefrom-with particular case and quicknose.

I claim as my invention: The combination with a two part tire rim separated circumferentially, the rim parts.

being constructedto centrally overlap and formed in theiroverl'apping portions with corresponding interspaced openings, of a spring ring inwardly formed with a fiat portion and with lugs bent at right angles 'from said flat portion, said lugs being interspaced and tapered" toward their free ends to extend through said openings and draw said rim parts together.

In testimony whereof I afix my signature in presence of two witnesses.
